Rhodope narrow railway train. Timetable, tickets, prices
A term «narrow railway» is directly related to the width of track gauge. In Bulgaria this type of railway is called a «tight ruler» (теснолинейка). Narrow railway is easier to build and cheaper to operate. The space between the rails in the Rhodope narrow gauge is only 760 mm, while the standard track size is 1520 mm. «Septemvri — Dobrinishte» is a last part of an old narrow gauge in Bulgaria.
